Good evening
I have a 400hz colpitts oscillator made from a PNP audio transistor(MF400 1 can’t finf this part number anywhere!!) 2 x 0.01uf caps
And a undefined audio choke(maybe a round 10 henries)
Which is not working, the dc resistance of the audio choke is 3.6 mega ohm’s
This seems unreasonable high, could this be the problem
Thanks
